Analyze CAN Bus with NI XNET

[dfschunk]

Hi all,

I work with an NI-PXI-8512 and LabVIEW Components fro the  NI XNET palette (LV Version 2013).

Communication over the Can-Bus functions very well (it's an automated test for software components).

Now I would like to get some data like busload, amount of error frames e.g. .

Does someone has some experience with this?

Thanks for your answers!

Hi dfschunk,

error frames can be read since the NI-XNET 1.7 driver. There are 2 options to read the error frames:

1. bus monitor:

Launch the bus monitor (start/all programs/NI XNET/). Start the feature: interface&database from the symbol bar, choose your CAN HW port. Now you can also select error frames.

2. LabVIEW VI

Error frames can be read, if you insert a XNET propertynode:Bus Error Frames to Input Stream. I attached a screenshot therefore.

The bus load is shown at the bus monitor.

Kind regards,

RupiDo

Hello everyone,

I am working with the same board PXI-8512, but when I start Bus Monitor i cannot see the interface CAN0,CAN1 (the way I named them on the MAX). I read others  old post and they said that it was not possible to use this program with a PXI or Compact RIO Board. I would like to know if it is possible.

I'm using Labview 2010 32 bits, i have the XNET library installed, but i used the CanOpen Library to communicate with a Motor Drive.

Thanks,

Juan Carlos Cambera

Hi I also want to know how to monitor the CAN busload with NI XNET?
